What is the idle fuel pressure?
Doing some trouble shooting on the fuel system, and I noticed the pressure at the rail is well over 50psi at idle.
That's considerably higher than my other cars-- is it correct?
Or do I have a regulator problem?

Often more importantly, under boost, fuel pressure at the rail needs to be 4 Bar (58 psi)plus the boost pressure, e.g. 22 psig boost = fuel rail pressure of 80 psig. Less than 80 psig, the injectors will run lean and you might have pinging issues.
